Detailed Description
The utility model is described in more detail below with reference to the accompanying drawings. The utility model provides a shock-absorbing puck which characterized in that: the connecting device comprises a disc-shaped upper hemisphere 1 and a disc-shaped lower hemisphere 2, wherein connecting columns 3 and connecting holes 4 are formed in opposite surfaces of the upper hemisphere 1 and the lower hemisphere 2, the connecting columns 3 and the connecting holes 4 are symmetrically arranged, and when the upper hemisphere 1 and the lower hemisphere 2 are assembled in pairs, the connecting columns 3 are inserted into the opposite connecting holes 4;
the upper hemisphere 1 and the lower hemisphere 2 are also provided with coupling holes 5 penetrating through the end surfaces of the upper hemisphere 1 and the lower hemisphere 2, and the connecting shaft holes are provided with connecting pieces 6 for axially limiting and connecting the upper hemisphere 1 and the lower hemisphere 2.
The diameter of the connecting column 3 is smaller than that of the connecting hole 4.
The connecting shaft holes are step holes arranged on the outer end surfaces of the upper hemisphere 1 and the lower hemisphere 2.
The connecting piece 6 is a rivet, the rivet penetrates through the connecting shaft hole 5, and the rivet joints at the two ends of the rivet penetrate into the connecting shaft hole 5.
The four connecting shaft holes 5 are uniformly distributed on the same circumference.
The outer end surfaces of the upper hemisphere 1 and the lower hemisphere 2 are provided with a first concave ring 7 and a second concave ring 8.
The outer cylindrical surfaces of the upper hemisphere 1 and the lower hemisphere 2 are provided with knurling patterns 9.
Working principle: as shown in fig. 1 and 2, the ice hockey in the present case is formed by mutually fastening and combining an upper hemisphere and a lower hemisphere, a connecting column 3 and a connecting hole 4 are arranged on opposite surfaces of the upper hemisphere 1 and the lower hemisphere 2, the connecting column 3 and the connecting hole 4 are symmetrically installed, and when the upper hemisphere 1 and the lower hemisphere 2 are assembled, the connecting column 3 is inserted into the opposite connecting hole 4. The diameter of the connecting column is smaller than that of the connecting hole, so that a certain amount of radial displacement can be realized between the upper hemisphere and the lower hemisphere after the upper hemisphere is buckled. In order to prevent the upper hemisphere 1 and the lower hemisphere 2 from being separated, a coupling hole 5 penetrating the end surfaces of the upper hemisphere 1 and the lower hemisphere 2 is further arranged, a connecting piece 6 is arranged in the connecting shaft hole, and the upper hemisphere 1 and the lower hemisphere 2 are in axial limiting connection. Wherein, the connecting piece is a rivet, and the rivet joints at the two ends of the connecting piece are used for being clamped in the connecting shaft hole 5 in an inward sinking manner. The rivet is installed without locking the axial displacement between the upper half shaft and the lower half shaft, so that a certain amount of axial and radial displacement exists between the upper hemisphere and the lower hemisphere. In the process of the ice hockey, the ice hockey is hit, and when the ice hockey is impacted, the displacement in two directions can effectively absorb the impact force, so that the ice hockey is effectively prevented from bouncing. In addition, the bidirectional displacement gap between the upper hemisphere and the lower hemisphere can also enable the ice hockey to offset the rotation potential energy, so that the ice hockey is prevented from rolling in the motion process, and the ice hockey is in sliding gesture motion when being contacted with the ground by the upper hemisphere or the lower hemisphere under high probability.
Further: in order to make the ice hockey sliding process smoother, a first concave ring 7 and a second concave ring 8 are arranged on the outer end surfaces of the upper hemisphere 1 and the lower hemisphere 2. The friction force between the ice hockey and the ground is reduced due to the arrangement of the concave ring, so that the ice hockey sliding effect on the ground is closer to the ice effect, and the dry-land training effect is improved.
Further: in the present case, the external cylindrical surfaces of the upper hemisphere 1 and the lower hemisphere 2 are provided with knurling patterns 9. The friction force of the ice hockey ball during beating can be increased, the beating stability is improved, the beating capacity and the beating accuracy of athletes are improved, and the training requirement is met.
The foregoing has shown and described the basic principles and main features of the present utility model and the advantages of the present utility model. It will be understood by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present utility model, and various changes and modifications may be made without departing from the spirit and scope of the utility model, which is defined in the appended claims.
